pectively, of the door Figure 9 is a perspective View of the door bricksupporting parts of the Figure 6, and,

door portion shown in Figure 10 is a perspective view'oi one of theparts shown in Figure 9, as seen from a different viewpoint. y

The coke oven illustrated in the drawings is one comprising horizontallyelongated coking chambers A and heating Walls B arranged side 5 by sidein a row in which the coking chambers alternate with the heating walls.The coke oven masonry is reinforced and supported at the sides of thebattery by a metallic armor, shown as com prising a flash plate G and acorresponding vertical buckstay D by which the flash plate is held inplace. Atl each end of each coking chamber end is a door frame member E.The latter preferably, and as shown, is in the formr of a one-piececasting extending l5 around the door opening, and of substantial horif.zontal depth measured in the direction of the length of the heatingWalls and coking chambers, the heating'walls being recessed at theirvertical corners as indicated at B to receive inner portions of thecorresponding door frame members E, each of which extend intothe ovenstructure and provides a metallic lining for the corresponding cokingchamber end.

As shown, each door frame member Eis anchored in place by adjustableclamping connections between its sides and the adjacent buckstay membersD. The clamping connections shown comprise parts d welded to thebuckstay members, and clamping levers F and bolts G. Each clamping leverF engages the corresponding door frame member E at one end, and at itsopposite end engages a corresponding part d andA is subjected to a`suitable clamping force by means of the corresponding clamping bolt G,which acts between the lever F and the" corresponding part d. In theconstruction shown, each door frame `member E includes adjustable flangeportions e at its sides which abut against adjacent edge portions of theadjacent flash plates G.

In the form illustrated in the drawings, each door comprises a rigidouter metallic frame section, which in the particular form shown,includes vertical channel bar members I-I at the opposite sides of thedoor, top, bottom,l and one 45 or more intermediate cross frame membersH', and other cross frame members I-I2 and H3, the cross frame membersbeing welded at their ends to the side frame members H. The cross framemembers H2 provide anchorages for the pivot 50 at each heating wall end,10

lock the door to and unlock it from said door frame member. The crossframe member H3 is provided for engagement by an operating part of theusual door handling machine (not shown) employed to move the door intoand out of its normal closed position in which the door extends into thedoorway.

The intermediate exible plate section or element of the door in the formshown in Figures 1-3 comprises a one-piece part K of metal plate, whichmay be a quarter of an inch or so thick and includes a substantiallyflat body portion, which in the closed position of the door extendsentirely across the door opening, and an integral inturned rim or liangeportion K' at the margin of said body portion, which then engages thesealing surface E formed on the corresponding door frame member E.

The plate member K is connected to and suspended from the outer framesection of the door at or adjacent the top of the door by means shown asincluding a horizontal shaft L, passing through and supported at itsends by heavy plate or lug parts welded to the head portions of thechannel bars H forming the side members of the rigid outer door framesection. The shaft L also passes through openings in brackets or lugs K6secured to the upper portion of the plate K, said openings preferablybeing horizontally elongated as shown. The lugs K are welded orotherwise secured to a horizontal channel bar K7 secured to the plate Kby bolts K8 which pass through the base portion of the channel bar K7and through the plate K and through a flange M of a casting or otherheavy metal part M thereby secured to the plate K. The member M extendsinto the oven chamber when the door is in its closed position shown inFigure 2.

In order to distort the sealing member K to ensure proper engagement ofits sealing edge K with the sealing surface E of the door frame memberE, a plurality of screws N are mounted at suitably distributed pointsalong the margin of the rigid outer frame section of the door. The headof each screw N engages a recess in a corresponding small pad orreinforcing part O welded to the outer side of the member K.

The intermediate sealing member or section and the clamping meansemployed to distort said sealing member form the subject matter of myBritish patent application No. 115 /36 from which the present inventionis divided.

The bricks or refractory blocks Q, Q' and Q2 constituting the bodyportion of the plug section of the door are stacked up on a rigidsupporting member R secured to the inner side of the body portion of themember K adjacent the lower end of the latter. As shown, the member Rcomprises a horizontal portion R on which the brick parts are stacked,and which, in the normal closed position of the door, rests upon thedoor sill portion e of the door frame member E. The memn ber R alsocomprises an uprising portion R2 adjacentthe plate K and detachablyconnected to the latter by bolts R3. Advantageously also, the member Rincludes gusset or side plate portions R4 at the opposite side edges ofthe door between which the brick parts at the bottom of the stack arereceived. The brick supporting portion R of the member R is formed atits upper side with a recessed seat R for a metallic post s. The latterextends to the top of the plug section of the door and has its upper endloosely received in a recess M2 formed for the purpose in the part M. Inthe preferred construction shown, the post s is of T bar cross-sectionwith the base of the section at the side of the post remote from thesealing member K.

The brick parts Q, Q and Q2 are suitably shaped to interlock with oneanother and with the post s which they collectively surround. As shown,one brick part Q and one brick part Q are located at each of a pluralityof different levels and constitute the body portion of the plug sectionbriokwork. One of the two parts Q and Q at each level extends from oneside of the plug section of the door into overlapping relation with thepost S and into abutting relation with the other part of the pair, whichis also in overlapping relation with the post S and extends to theopposite side of the door. As shown, each ofthe parts Q and Q includes aportion q at the outer side of the door extending into proximity withthe web or leg of T bar section of the post S and extending in front ofthe corresponding portion of the head of the post section. Each brickpart Q' includes a portion at the inner side of the post extending pastthe latter.

The brick parts Q and Q' are each recessed to receive a correspondingportion of a corresponding brick part Q2 by which the brick parts Q andQ are locked in place about the post S. As shown, the bricks Q and Q ineach of two adjacent horizontal layers or courses, collectively form ahorizontal channel extending from the inner side of the door to theadjacent side of the post S, and shaped to receive and be filled by acorresponding brick part Q2. Each brick part Q2 is formed with angeportions` or ribs extending horizontally in the direction of the dooraxis and projecting away from the top and bottom faces of the brick Q2at the side edges of the latter. Each brick Q2 is thus in effect a tenondovetail part interlocking with two brick parts Q and two brick partsQ', all of which are thereby held against significant horizontalmovement relative to the post S. Since in the normal manipulation anduse of such doors the latter are maintained vertically or substantiallyso, it is not necessary to provide interlocking provisions preventinghorizontal movement of the locking brick parts Q2 away from the T bar S,between which and the inner face of the plug door section, each part Q2extends. Friction is sunicient to hold those parts in place, even thoughthe plug section brick parts are not laid with mortar, which may or maynot be used.

The particular door shown in Figures 1, 2 and 3 is a pusher side door,and is provided at its top with a casting h for the usual levelling baropening or doorway ordinarily provided in pusher side doors. As will beapparent to those skilled in the art, the seat for the upper end of thepost S might be formed by a recess in the casting h, but I consider itpreferable to provide a special part M as shown, in which the upper endof the post has its seat. In the preferred construction illustrated, thetop bricks Q and Q and a portion of the interlocking brick Q2 are abovethe top of the post S, the bricks adjacent the part M being speciallyformed or chipped away to provide space for that part. The details justmentioned and the differences in respect thereto between the coke sideand pusher side doors are without real significance in so far asconcerns the essentials and principles of the present invention.

The brick parts Q, Q', and Q2 are disposed so as not to interfere withsome relative movement of the post and brick parts as the door is heatedand cooled. To this end, cardboard of suitable thickness mayadvantageously be interposed between the post S and the adjacent bricksurfaces in the initial assembly of the door. To insure suiicientiiexibility and freedom for adjustment of the sealing member part K, thelatter is suitably spaced away from the outer face of the plug sectionof the door, and to this end cardboard o1 suitable thickness may well beinterposed between the plate K and the plug section of the .10 door inthe initial assembly of the latter.

In the door construction illustrated in Figures 5 to 10 the intermediatesection or plate KA has welded to its edges a sealing flange or strip Khaving its inner edge bevelled off at K11 and a '1'5 plurality ofadjustable clamping devices N10 are provided which connect the flexibledoor element KA to the rigid outer frame section I-IA.

In the construction of Figures 5-10, the iiexible element is suspendedfrom a shaft L carried by the outer frame member, exactly as in theconstruction first described, but preferably the flanged bar K7 carryingthe hinge lugs K0, is welded to the plate KA, or is secured to thelatter by bolts or rivets separate from the bolts M11, which areemployed to detachably connect to the plate the part M10, shown inFigure 8, which replaces the part M previously described. The platemember KA carries at its lower end a rigid brick supporting member R10,similar in its general 30 purpose, and shown as generally similar inform, to the part R of the construction first described. In theconstruction shown in Figures 5-10, however, the bricks forming therefractory portion of the door, do not bear directly against thehorizontal lower portion of the member R10, but on a removable castingplate T. The latter, as is plainly shown in Figures 9 and l0 is formedwith a notch T receiving the bar S in the assembled condition of theplug section of the door. The plate T is also formed with notches T2 inits opposite side edges which, in the assembled door, receive lugs orprojections R0 of the member R at the bottom of the latter and therebyhold the plate T against horizontal movement relative to the supportingcasting R10. While the notch T is shaped to permit free movement of theplate transversely of the bar into and out of its normal relationtherewith in the assembled condition of the plug section, the plate T isinterlocked against movement relative to the bar by a transverse plateor foot part S10 welded to the lower end of the bar and normallyreceived in a recess T3 formed in the underside of the plate T. rEhebrick parts of the plug section shown in Figures 6 and 8 comprise brickparts Q10 and Q11 which may be exactly like the brick parts- Q and Q2previously described, and are similarly interlocked by brick parts Q2.As shown in Figure 7 a specially shaped head brick Q13 forms the top ofthe plug section of the door being recessed at its end side to receivethe upper end of the bar S. The previously mentioned metallic part M10is interposed between the head brick and the subjacent bricks which arerecessed to receive the plate and the latter has welded to its outeredge the previously mentioned bolts M11 by which the plug section of thedoor is detachably secured to the intermediate exible section or elementof the door.

As will be readily apparent, the plug section of the door, except forthe head brick Q13, may be readily assembled to form the unit shown inFigure 9 with the bar S vertically disposed, or, conveniently in somecases, with the bar S horizontally disposed in an assembly rack orcradle not shown, but adapted to facilitate the assemblage of the brickand metallic parts. The unit thus formed may be transported bodily as bymeans of a crane or hoist having a hook adapted to enter the hole S12formed for the purpose in the upper end of the bar, the foot portion S10then preventing down movement of the refractory blocks and plate T,relative to the post S. The plug section unit may thus be readily movedinto and out of its normal position at the inner side of the member KA.In they normal condition of the door, the plug section is held againsthorizontal movement relative to the casting R10 by the projections R6 ofthe latter received 'in the notches T2, while the top of the plug isanchored in place by the part M10, through which the bar S passes, andthe bolts M11 by which the part M10 is detachably secured to the memberKA. `The head brick may be readily put into place or removed to exposethe hole S12 in the bar S when occasion requires.

The door shown in Figure 5 is intended for use at the coke side lof thebattery at which the coke is discharged, and hence does not includeprovisions such as the casting h of the pusher side door constructionfirst described, for a levelling bar or poke hole. As those skilled inthe art will understand, the special features of each of the doorconstructions illustrated, may be used equally well in a pusher sidedoor, as shown in Figure 2, or in a coke side door as shown in Figure 5.

Certain novel features of coke oven door construction and arrangementdisclosed, but not claimed herein, are disclosed in one or the other ofmy prior applications, Ser. No. 977, filed Jan. 9, 1935, and Ser. No.52,995, filed Dec. 5, 1935,' the present application being in respect toa portion of its subject matter, a division of one of said priorapplications and being a division of the other of said priorapplications in respect to the remainder of its subject matter.Accordingly, the present case may be termed a continuation-in-part ofeach of the two above mentioned applications.

While in accordance with the provisions of the statutes, I haveillustrated and described the best forms of my invention now known tome, it will bei apparent to those skilled in the art that changes may bemade in the form of the apparatus disclosed, without departing from thespirit of my invention as set forth in the appended claims, and that insome cases advantageous use may be made of some features of the presentinvention without a corresponding use of other features.
